I rebuilt my 5.7 liter v.8 and I can't figure it out. It runs fine when it is cold but cuts out when it warms up. I suspect it is a timing issue because it keeps sending a trouble code saying the cam sensor and crank sensor are not corralating. The sensors work fine. Unless they are not working properly which I cannot test for.

The timing on these engines cannot be set without using a scan tool capable of doing so. Your timing is probably off a little. Unless you have a $15000 scan tool, a dealer is usually the only place that has a scan tool capable of setting the timing. Also if you replaced the crank sensor you should have a crank relearn procedure done at the dealer also.
